Filter technology for stainless steel pipe fittings

Surface filtration Surface filtration is accomplished by particles of solid contaminants that are trapped on the pores or channels of a single plane or surface. Filtration occurs only on this surface, and contaminants that do not remain on this surface continue through the filter mediator. Surface filtration can effectively collect particles larger than the pore size, but it cannot collect fibers and particles smaller than the L size of the hairpin. The pollutant capacity of a surface filter is limited by the total surface area, and the surface area fork cannot exceed a given outline size. Examples of surface filtration mediators are single-layer mesh filters, stacked gaskets, wound metal tapes, and perforated metal sheets.

Deep Filtration Deep Filtration is accomplished by the collision of solid contaminants while remaining on a matrix of continuous (or deep) pores. Sand is a typical example of a depth filter. Its filtering effect is its random adsorption and the role of trapping solid pollutants. The filtering is performed not only on the surface of the mediator, but also across the entire thickness of Jiexiu. The particles passing through the matrix change their direction from time to time along a circuitous route. The depth filter can effectively collect particles and fibers with the largest pore size of large stems. At the same time, due to the type and thickness of its filter media, it can also collect some pollutants smaller than the maximum pore size. The capacity of contaminants per square inch of surface area of ​​a depth-type filter mediator is too high, because the contaminants can be left over the entire depth of the material in addition to the surface layer of the mediator. Examples of deep filter media are multilayer gangs, wire wound cylinders, laminated paper discs, sintered granular materials, multilayer braids, pressed or woven organic or inorganic fiber boards, laminated etched metal discs, Open cell foam and laminated film.
